Miniature rose plant named ‘HOHOEMI ROUGE’

ABSTRACT

A new and distinct variety of Miniature Rose Plant, herein referred to by its cultivar name, ‘HOHOEMI ROUGE’, is provided which forms in abundance on a nearly continuous basis attractive, small dark deep pink colored blossoms. The vegetation is vigorous and the growth habit is bushy. Attractive ornamental dark green foliage is formed. Disease tolerance to Black Spot and Rust is good. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification:

Latin name: Rosa hybrida.

Common name: Miniature Rose Plant.

Varietal denomination: ‘HOHOEMI ROUGE’.

CROSS-REFERNCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2018/2421, which was filed in the European Union on Sep. 24, 2018, and to Plant Breeders' Right Application Number 32561, which was filed in Japan on Nov. 1, 2017, the contents of which are hereby expressly incorporated by reference in their entirety for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida miniature rose plant of the present invention was discovered during Spring 2015 at Honjo City, Saitamam pref. Japan. The new variety is a spontaneous mutation of the ‘AYA NO5’ variety (not patented) and was selected and preserved primarily because of its color difference from the ‘AYA NO5’ parent variety.

The parentage can be summarized as follows: spontaneous mutation of ‘AYA NO5’

It was found that the new miniature rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) displays a multitude of small, dark deep pink flowers,     -   (b) forms attractive ornamental dark green foliage,     -   (c) forms vigorous vegetation, and     -   (d) exhibits good tolerance to Black Spot and Rust.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the ‘AYA NO5’ variety (i.e., the parent) exhibits light pink colored flowers, whereas the new variety displays dark deep pink colored flowers.

The new variety has been found to undergo asexual propagation in France by a number of routes including budding, grafting, and cutting. Asexual propagation in France by these routes has shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘HOHOEMI ROUGE’.

A new and distinct miniature rose plant characterized by the following combination of characteristics: (a) displays a multitude of small, dark deep pink flowers, (b) forms attractive ornamental dark green foliage (c) forms vigorous vegetation, and (d) exhibits good tolerance to Black Spot and rust; substantially as herein shown and described.
